名  称：硅石矿石

主要成分：化学成分为SiO2，岩性为脉石英，含少量绢云母和微量金红石、锆石、电气石。

成  因：岩浆分泌的SiO2溶液沿构造裂隙充填形成。

主要用途：制高纯度石英粉，是光学玻璃与艺术玻璃的重要硅质原料；高纯石英粉可用于生产多晶硅和单晶硅。

采集地点：内蒙古正蓝旗马牙子山硅石矿

Name：Silica Ore

Composition：Chemical composition SiO2，rock type quartz vein, containing minor sericite, and trace amount of , zircon and tourmaline.

Genesis：Infilling of SiO2solution along fractures, which was released from magmas.

Usage：For making high purity quartz powder, which is the major raw material for making optic and art glass. High purity quartz powder can be used in making monocrystalline silicon and polysilicon.

Sample site：Mayazi Mt Silica mine, Zhenglanqi, Inner Mongolia.
